PolyamidesUn polyamide est un polymère contenant des fonctions amides -C(=O)-NH- résultant d'une réaction de polycondensation entre les fonctions acide carboxylique et amine.
Selon la composition de leur chaîne squelettique, les polyamides sont classés en aliphatiques, semi-aromatiques et aromatiques. Selon le type d'unités répétitives, les polyamides peuvent être des homopolymères ou des copolymères.

Solidité de la couleurIndex. décimale : 667.2 Colorants et pigments Résumé : Ultrafine polyamide/polyurethane synthetic leather (UP/PSL), with a highly natural leather-like appearance and touch, is widely used in many leather commodities. Generally, acid dyes, which are mostly used for dyeing UP/PSL, exhibit poor colour fastness. While, reactive dyes are well-known for their good colour fastness. However, reactive dyes are not used to dye UP/PSL because they are water-soluble and cannot stain the polyurethane (PU) in UP/PSL. In this study, five low water-soluble reactive dyes with good affinity for both polyamide (PA) and PU were synthesised and characterised using ultraviolet-visible and infrared spectroscopy, and mass spectrometry. All low-water-soluble reactive dyes were monoazo dyes with only one sulfonic group and two different functional groups. The reactive dyes were used to dye UP/PSL at 98°C and fixed at 90°C with 7-azatridecane-1,13-diamine as a crosslinking agent. For comparison, Eriofast Red-2B (ER-2B) was used to dye UP/PSL using a special dyeing procedure. ER-2B showed severe issues related to low utilisation and uneven dyeing, whereas the five low water-soluble reactive dyes exhibited better performance than ER-2B. Both the exhaustion and fixation of dyes 1 and 4 exceeded 90.0% when the dosage was less than 3.0% owf (on weight of fabric). In addition, they exhibited good levelling. The washing fastness of the five reactive dyes was excellent and higher than grade 4. The dry rubbing fastness was higher than grade 3-4. Therefore, UP/PSL can be satisfactorily dyed using the reactive dyes with a solubility of less than 1.0 g/L and meet the requirements of daily life applications.

Teinture au tamponIndex. décimale : 667.2 Colorants et pigments Résumé : The practical application of a sulphur black dye relies on its ability to dye cotton fibres with pure black colour and maintain the colour with high light fastness. Here, we report a synthesis method to prepare a novel water-soluble reactive sulphur black dye. The approach involves the reduction of CI Sulphur Black 1 to its leuco form and subsequent reaction with a water-soluble intermediate containing reactive groups synthesised from amino acid and cyanuric chloride. The optimal carboxyl and reactive group content of the water-soluble reactive sulphur black dye is 141 mmol/100 g, and the water solubility can reach 92 g/L. The fixation of the reactive sulphur black dye on cotton reaches 89% in a pad dyeing process without using sodium sulphate. The reactive sulphur black dye can achieve a light fastness of grade 6-7, a dry rub fastness of grade 4 and a wet rub fastness of grade 2, comparable or higher than the conventional CI Sulphur Black 1. The dyeing results showed that the novel water-soluble reactive sulphur black dye has excellent performance and good application prospects.

Teinture -- Fibres textilesIndex. décimale : 667.3 Teinture et impression des tissus Résumé : A new kind of hetero-bifunctional reactive dye containing 2-ethoxy-4-chloro-s-triazine, with better activity matching with β-hydroxyethyl sulphone sulphate at a low fixation temperature, was successfully synthesised and characterised. An ethoxy group was designed to be introduced into triazine to increase the substantivity and the reactivity of the dyes. Thereby, the fixation of mono-s-chlorotriazine/hydroxyethyl sulphone sulphate (KM-type) bifunctional reactive dyes on cotton was improved, and dyeing under mild conditions with high fixation was realised. Nineteen dyes with orange, red and blue colours were synthesised and characterised by UV-Vis and infrared spectroscopy and mass spectrometry. Synthesised dyes were dyed at 60, 75 and 90°C, respectively. Exhaustion and reactivity for all of the ethoxy-containing KM-type dyes was over 90% at the optimal temperature, and fixation was over 87%, which was higher than the ethoxy-free comparative dyes. The optimal fixation temperature of ethoxy-containing dyes was initially reduced to 75°C, and then to 60°C. Compared with comparative dyes, the wash fastness and light fastness were basically unchanged, and the wet rub fastness of the H-acid series was reduced by one grade.

Teinture -- Fibres textilesIndex. décimale : 667.2 Colorants et pigments Résumé : To obtain a new type of macromolecular reactive dye with high fixation and good light fastness, poly(styrene-co-maleic acid) was synthesised by co-polymerisation of styrene and maleic anhydride, then, through nitration, reduction, diazotisation and coupling reaction, novel macromolecular reactive dyes were prepared with a solubility greater than 60 g/L. The dyes were used to dye cotton fabrics; the results showed their fixation was more than 92%, and both the rub and wash fastness of the dyes were good. The light fastness of the red and blue dyes with the ethoxy group on melamine was grade 4, and for the yellow dye reached grade 5. The poly(styrene-co-maleic acid) macromolecular reactive dyes exhibit very good application prospects in practice.
